EMT Airway and Breathing Practice Test 2
The inability to move enough air required for adequate perfusion is known as what?
Respiratory failure is a medical term for inadequate gas exchange by the respiratory system. Respiratory failure can be indicated by observing a drop in O2 saturation and breathing rate / quality.
What is the proper amount of air that should be injected to the cuff of an Endo Tracheal Tube?
The standard ET Tube cuff is inflated with 10 cc of air
A blue or greyish coloration of the skin caused by lack of oxygen in the blood is called?
Cyanosis occurs when the oxygen saturation of arterial blood falls below 85-90%. It is often presents in the lips and nail beds first.
Cyanosis can be checked by observing the patient's _______?
Early signs of cyanosis often presents more clearly in the nail beds and lips
Two large tubes that bring air to and from the lungs are known as what?
The Trachea leads to the Bronchi which lead into the Bronchioles.
Which is NOT a correct technique for confirming correct ET Tube placement?
Seeing movement of the chest wall does not guarantee proper tube placement because inflating the stomach could be mistaken for chest rise.
What term refers to the expansion of the stomach caused by excessive ventilation pressures, which causes excess air to enter the stomach instead of the lungs?
Gastric Distention should be avoided as it often leads to vomiting and aspiration of said emesis.
Which medication that will open bronchioles and increase effectiveness of breathing is typically used to treat a patient with shortness of breath?
Bronchodilators are used to dilate or widen the bronchioles allowing air to more easily flow through them. A common bronchodilator is Albuterol.
What condition is characterized by a high pitched sound resulting from turbulent air flow in the upper airway? It may be inspiratory, expiratory or present on both inspiration and expiration.
Stridor is indicative of a severe upper airway obstruction.
What condition is characterized by gasping, labored breathing, and strange vocalizations?
Agonal respirations are also commonly seen in cases of cardiac arrest, and may persist for several minutes after cessation of heartbeat.
The space between the base of the tongue and the epiglottis is called?
The Vallecula is an important landmark in intubation; it is where the blade of a laryngoscope is placed to facilitate direct visualization of the glottis.
You are performing rescue breaths using an Ambu bag attached to 100% O2. After several breaths you notice the patients O2 saturation has dropped significantly. What should you do next?
This is a sign that you are not getting effective respirations. You should reposition the patient's head using the head tilt / chin lift or jaw thrust maneuver and attempt respirations again.
What is the maximum amount of time that may pass while attempting an intubation?
If you are unsuccessful with your intubation, you should always cease your attempt after 30 seconds, allow for the patient to be hyperventilated and attempt it again.
An oral and nasal airway should be:
When a patient is unconscious, the tongue has a tendency to fall back in the mouth and block the airway. An oral or nasal airway is used to prevent this.
Which of the following is NOT a sign of adequate breathing?
Using abdominal muscles to breath is a sign of labored breathing NOT of adequate breathing.
